Flex separation systems, S separators 921–987 Cleaning systems for heavy fuel oils* Separator Change-over valve Water block Flex system components for S separators 921–987. Oil block including water transducer * S separators can also be used to clean lighter fuel oils and lubricating oils. S and P Flex separation systems Alfa Laval’s S and P Flex separation systems com ine the b high efficiency, low sludge output and low operating cost of Alfa Laval centrifugal separators with a flexible scope of supply. Extensive possibilities for the separation system layoutand assembly make it possible to suit any engine room and any oil separation application. Application S separators S separators are based on Alcap technology, which means they automatically adjust the oil/water interphase based on the water content in the clean oil outlet. This makes them particularly suitable for separating heavy fuel oils with varyingdensity, though they can be used to clean all of the following: In addition, S and P Flex separation systems feature the EPC 60 controller, which enables the intuitive navigation of menus, parameters and alarms. The EPC 60 controller also has a modular construction for easy I/O board addition and replacement. • eavy fuel oils with densities up to 1 010 kg/m3 and H viscositiesup to 700 cSt/50°C (higher viscosities available upon request) • Lubricating oils • Distillates • Lighter diesel oils The S and P Flex separation concept includes the complete S- and P-separator range. These can be combined in mixed ship sets, even within a single customer-specified module. S separators are designed for automatic operation in periodically unmanned engine rooms at sea and in automated

Scope of supply The S and P Flex separation concept provides a wide range of alternatives for S separators. Depending on the need, a S separator can be supplied as a separator and ancillaries, as a customer-specified module, or as part of a comprehensive ackage including services p and order-specific documentation. These S separators come equipped with energyefficient IE3 motors. Module examples Single Flex module with separator (excluding heater and pump) Single Flex module with separator, heater and pump Flex system A S separator with ancillaries in the form of optimized block...

Water inlet 5. Pneumatically controlled change-over valve 9. Pneumatically controlled shut-off valve Operating principle A Flex separation system based on an S separator 921-987 is operated automatically by the EPC 60 controller. Untreated oil, heated to the correct temperature, is fed continuously to the separator, which is driven by an electric motor via a friction clutch and belt. The separator bowl is fixed at the top of a spindle, which is supported by bearings and special composite springs. During operation, separated sludge and water accumulate at the bowl periphery and are...

CentriShoot Instead of a sliding bowl bottom, the CentriShoot discharge system features a fixed discharge slide that flexes at its edge. This increases discharge accuracy and does away with metal-to-metal wear. CentriLock Conventional lock rings are threaded and must be removed with a sledgehammer. Over time, the metal-to-metal wear between bowl and lock ring can lead to expensive bowl repair or replacement. Step one: The CentriShoot discharge slide is fixed at the centre. During separation, the slide covers the discharge ports. An Allen key is the only tool needed to work with CentriLock....
